Abstract

The invention discloses a seamless steel tube mill retracting device which comprises a machine base and a trolley sliding rail which is arranged on the machine base. A rolled tube core rod trolley is arranged on the trolley sliding rail and connected with a gantry frame. Oil cylinder bases are arranged on the machine base and on the two sides of the trolley sliding rail. Hydraulic oil cylinders connected with a hydraulic station are arranged on the oil cylinder bases. The drive ends of the hydraulic oil cylinders are connected with the two sides of the gantry frame. The seamless steel tube mill retracting device adopts two sets of hydraulic oil cylinders to carry out driving. The seamless steel tube mill retracting device is stable and reliable in operate, reduces the fault rate, improves the production operation rate and the retracting precision and ensures the milling quality.

Description

A kind of seamless steel tube rolling mill backspace mechanism
Technical field
The present invention relates to a kind of seamless steel tube rolling mill, relate in particular to a kind of seamless steel tube rolling mill backspace mechanism.
Background technology
In process of production, the pipe mill backspace mechanism, fixing and mobile device as the tube rolling mandrel trolley, when limit rolling, limit rollback, existing design is to carry out rollback by large tooth bar, because there are mechanical oscillation in rolling, large tooth bar is easy to wear and easily jump tooth, has that fault rate is high, the low shortcoming that affects product quality of rollback precision.
Summary of the invention
The object of the present invention is to provide a kind of seamless steel tube rolling mill backspace mechanism, it has failure rate is low and the high characteristics of rollback precision, to solve the problems referred to above that in prior art, the seamless steel tube rolling mill backspace mechanism exists.
For reaching this purpose, the present invention by the following technical solutions:
A kind of seamless steel tube rolling mill backspace mechanism, it comprises support and is arranged at the dolly slide rail on support, be provided with the tube rolling mandrel trolley on described dolly slide rail, wherein, described tube rolling mandrel trolley is connected with portal frame, be provided with the oil cylinder pedestal in the both sides of dolly slide rail on described support, the hydraulic jack that connects Hydraulic Station is installed on described oil cylinder pedestal, the drive end of described hydraulic jack connects the both sides of described portal frame.
Especially, the drive end of described hydraulic jack is connected with cylinder connector, and described cylinder connector is articulated on portal frame by Connection Block.
Especially, the top of described tube rolling mandrel trolley is equipped with connecting plate, by connecting plate, the tube rolling mandrel trolley is connected with portal frame.
Beneficial effect of the present invention is, compared with prior art described seamless steel tube rolling mill backspace mechanism adopts two cover hydraulic jacks to be driven, and not only stable and reliable operation, reduced fault rate, and improved production operational availability and rollback precision, guaranteed rolling quality.
